I have a machine that multi-boots with separate ata disks for each OS. 
I'd like to have FreeBSD (5.1) spin down the other disk to reduce heat
and noise, since it doesn't use it at all.  I haven't been able to find
anything in the apm, ata, or acpi documentation I could find.  How do I
accomplish this?
